narcolepsy to help them to stay awake.
Narcolepsy is a condition that causes excessive
daytime sleepiness and a tendency to fall asleep
suddenly in inappropriate situations (sleep
attacks). Modafinil may improve your narcolepsy
and reduce the likelihood that you will have sleep
attacks but there may still be other ways that you
can improve your condition and your doctor will
advise you.

1. What Modafinil is and what it is used for

Modafinil and certain other medicines can affect
each other and your doctor may need to adjust
the doses that you are taking. It is especially
important if you are taking any of the following
medicines as well as Modafinil:
• Hormonal contraceptives (including the
contraceptive pill, implants, intrauterine
devices (IUDs) and patches). You will need to
consider other birth control methods while
taking Modafinil, and for two months after
stopping treatment, because Modafinil reduces
their effectiveness.
• Omeprazole (for acid reflux, indigestion or
ulcers).
• Antiviral medicines to treat HIV infection
(protease inhibitors e.g. indinavir or ritonavir).
• Ciclosporin (used to prevent organ transplant
rejection, or for arthritis or psoriasis).
• Medicines for epilepsy (e.g. carbamazepine,
phenobarbital or phenytoin).
• Medicines for depression (e.g. amitriptyline,
citalopram or fluoxetine) or anxiety (e.g.
diazepam).
• Medicines for thinning the blood (e.g.
warfarin). Your doctor will monitor your blood
clotting times during treatment.
• Calcium channel blockers or beta-blockers for
high blood pressure or heart problems (e.g.
amlodipine, verapamil or propranalol).
• Statin medicines for lowering cholesterol (e.g.
atorvastatin or simvastatin).
Pregnancy and breast feeding
If you are pregnant or breast feeding, think that
you may be pregnant, or are planning to have a
baby, ask your doctor or pharmacist for advice
before taking this medicine. You should not take
Modafinil. It is not known if your medicine may
harm your unborn baby.
Talk to your doctor about the birth control
methods that will be right for you while you are
taking Modafinil (and for two months after
stopping) or if you have any other concerns.
